Service history[edit]

Inter-War Period[edit]

After shakedown, Porpoise transited the Panama Canal and joined the Pacific Fleet at San Diego on 1 September 1936. After gunnery and torpedo practice off the west coast of the United States, she participated in Fleet Problem XVIII in the Hawaiian area, April–May 1937, and toward the end of the year underwent extensive overhaul at Mare Island Navy Yard. In January 1938, she returned to Pearl Harbor for fleet exercises, and on 19 November 1939 got underway for Manila to join the Asiatic Fleet. From December 1939-December 1941, she was engaged in various exercises with Submarines, Asiatic Fleet.

World War II[edit]

At the outbreak of the war with Japan on 7 December 1941, Porpoise - commanded by Joseph A. Callaghan - was at Olongapo, P.I., undergoing a refit. With all four main engines being overhauled and her entire after battery out, the required work was accomplished in record time. She moved to Manila on 20 December, and two days later was underway on her first war patrol - from 22 December 1941–31 January 1942 - in Lingayen Gulf and the South China Sea off French Indochina. Retiring by way of Balikpapan, Borneo, where the Dutch were demolishing their oil wells, Porpoise attacked two ships without result before ending her patrol at Surabaya, Java.

Conducting her second war patrol in the Netherlands East Indies - from 9 February–30 March - she scored on a cargo ship before anchoring at Fremantle, Western Australia. Then, with the ultimate destination of Pearl Harbor, she returned to the Netherlands East Indies for her third war patrol - from 26 April–17 June. She made one unsuccessful attack on a cargo ship and rescued five airmen off the enemy held island of Ju before heading out across the Pacific.

After a major overhaul at Mare Island, Porpoise departed Pearl Harbor for her fourth war patrol - from 30 November 1942–15 January 1943 - off the coast of Honshū, Japan. On 1 January 1943, she sank Renzan Maru, then set course for Midway where she completed the patrol. Her fifth war patrol - from 6 February–15 April - off Jaluit Atoll, was highlighted by the sinking of Koa Maru on 4 April., and by an unsuccessful attack on the unarmed Japanese hospital ship, Takasago Maru on 8 April.[11]

After refit at Pearl Harbor, Porpoise sailed on her sixth patrol - from 20 June–28 July - performing reconnaissance of Taroa Island and in the Marshall Islands. Scoring hits on two cargo ships early in her patrol, she then sank Mikage Maru No. 20 on 19 July before returning to Pearl Harbor.

Due to leaky fuel oil tanks Porpoise departed Pearl Harbor for New London, Connecticut, where she was to be used as a training vessel. She arrived in September 1943, and interrupted only for overhaul at Philadelphia from May–June 1944, she served on this duty until inactivated. She decommissioned on 15 November 1945 at Boston, and remained in reserve until 8 May 1947, when she was placed in service and assigned to the 8th Naval District. For the next nine years she trained Naval Reservists in the Houston, area. Stricken from the Naval Vessel Register on 13 August 1956, she was sold for scrap to Southern Scrap Material Co., Ltd., New Orleans, on 14 May 1957.

Awards[edit]

Porpoise earned five battle stars for her World War II service.
